Gardner Spring MB0250-013-S Belleville Disc Spring

Product Description

The GARDNER SPRING MB0250-013-S is a Belleville disc spring designed to deliver precise axial load in compact, space-constrained assemblies. Manufactured from stainless steel, this conical washer-style spring measures 0.25 inches in outer diameter and 0.125 inches in inner diameter, with an overall assembled height (OAH) of 0.02 inches. It provides a load of 5.85 pounds at a deflection of 0.0945 inches, making it well suited for applications requiring consistent spring force in a very small footprint. Licensed mechanical and industrial technicians as well as precision assembly professionals are the typical installers of this component.

This Belleville disc spring is used in mechanical assemblies where axial preload, vibration damping, or controlled deflection is required within tight dimensional constraints. Its stainless steel construction makes it appropriate for environments where corrosion resistance is a priority, such as HVAC equipment assemblies, plumbing valve components, and industrial fastening systems requiring a 1/8-inch bolt size. The small form factor allows stacking in series or parallel arrangements to tune load and deflection characteristics for specific design requirements.

Key Features

• Stainless steel construction for corrosion resistance in demanding environments
• 0.25 inches outer diameter and 0.125 inches inner diameter for 1/8-inch bolt compatibility
• 5.85-pound load capacity at 0.0945 inches deflection for predictable spring performance
• Low-profile OAH of 0.02 inches supports space-constrained installation scenarios
• Stackable design allows series or parallel configurations to modify load and deflection

Compatibility

Designed for use with 1/8-inch bolt-size applications. Designed as an OEM-style replacement or component-level addition in assemblies requiring a 0.25-inch OD Belleville disc spring with stainless steel construction.

Installation Notes

Installation of Belleville disc springs should be performed by a qualified mechanical technician familiar with spring-loaded fastener assemblies. De-energize and depressurize any system before servicing components that incorporate this spring. Verify stacking orientation - series and parallel arrangements produce different load and deflection results - and confirm the correct configuration before final assembly. Avoid exceeding the rated deflection, as over-compression can cause permanent set and loss of spring function.
